CUT-OUT VALVE.

Application mea August 4, V1924. serial No. 7293908.

This invention relates to cut-outvalvesintended to be used to divert theexhaust gases from an automobile engine into a pipe leading to aradiator for heating the car. By my improvement I am able to manufacturea standard cut-out valve to beuscd in fitting exhaust pipes of varioussizes to accommodate different makes of automobiles, and at the sametime to make a certain and accurate it of the valve upon the valve seatto prevent leaking of exhaust gases about the valve, as well as at theconnection between the cut-out and the exhaust pipe, to further renderthe connection between the usual elbow connected with the heater pipeand the opening in the exhaust pipe, positive.

It is an object of my inventionto provide such elbow with longitudinalprojecting flanges to which' the flexible attaching plate may be securedby screws or rivets and further making possible the provision of f aslight rib on the elbow or other casting adjacent the opening therein toprevent the gas escaping around the edges of the valve seat.

It is a further object of my improvement to provide bosses at thecorners of the elbow opening upon the casting to accurately position thecasting upon the exhaust pipe and thus make certain the proper sizes ofthe pipe opening to make possible the required movement of the valve.

It is a still further object of my invention to connect the valvetongueto the valve'lever for actuating it by Weldingthe formerrto the latter,and to do such welding while the parts are in tongue in perfectregistration uponthe valve seat, so that the accurate seating of thevalve' y may not depend entirely upon the accuracy ofthe machine work,thus further lproviding for a leak-proof condition aboutthe valve.L`With these and other objects in view I' have described my structurehereinafter, recited'it in the appended claims and illus'- trated it inthe accompanyingdrawings in which- 1 Figure 1 is a side tion; y

My invention intended to be used with various automobile yheatersdesigned to be heated'by exhaust gases to be diverted from the mainexhaust pipe from the engine.

'A portion of an exhaust in the drawings, from which an elongatedsection'has been cut forming an opening 13 pipe 10 is shown I havingparallel lateral edges and curved end edges. one end of an open-endedcasing, such as an elbow 11 the bore of whoseelongated opening-14= shalregister with that of the opening 13. The lower end 12 ofthe elbow 11 isprovided with horizontal side flanges or wings 15 castl integraltherewith. Forwardly, these flanges extend just iush with the wall ofthe elbow, whilel at the rear they project sufficiently to form byuniting, an

outer wall 9 extending upwardly and for-V wardly to unite with the mainwall of the elbow at 8,.thereby forming parallel side walls 7 integralwith the ,wall 9.

The opening 14 is restricted rearwardly by an over-hangingintcgralflange or lip 20 curved to conform to vthe shaft 1.9 about which itextends for an arc of about. 9()O within the elbow,` to outline a'smaller open-V kIn this opening I propose to seatv ing 6 into theelbow, this opening constituting ythe valve seat. The valve 18 closesthis y thereto, and is-pivoted at its rear end upon the shaft 19. Theend of the opening nearest the engine is rounded,

and the edges slightly'rabbeted orbeveled. .y

The rear end 16 of integral with the main elbow casting andv with thelip 20.- In my construction, the

lrock shaft 19 is journaled in bearings inthe side-walls of the elbowand is positioned in the groove or trough 21 formed between parts `land20, and the latter extends down to' the yhorizontal plane through thelower edge of the shaftloreven lower, thus the axis of the shaftwill bemuch higher than the lower edge of the .lip 20. In fact, it is mypurposeto seat the valve and its pivotal axis well up in the elongated openingof the elbow, as rshown in Figs. 2,. 3 and 4, so that it will be wellprotected from the gases rushing throughf the exhaust pipe, except whenthe' valve is open. i yThe .shaft 19 ismounted above and over the baseof the elbow is i and pipe,

in the exhaust pipe when the valve is closed.

The usualmeans for actuating the lever 22and the shaft 19 with its valveis provided for, the flexible wire 23 leading forwardly by means ofwhich the shaft may be rocked and the valve opened or closed. A furtheradvantage arises from the mounting of the shaft 19 far above the flanges28 so that the shaft 19 does not perforate the sheet 27 at any pointwhatever, thus avoiding a former disadvantage of the loose rocking ofthe shaft in a flexible attaching sheet and permitting escape of gasesthrough the apertures.

It is understood that difficulty has been experienced in the past inmaking a leakproof connection between a branch pipe and an aperturedexhaust pipe, at the same time providing a valve fitting accurately uponits seat, without incurring additional expense in machining. I do notclaim the provision of a flexible plate intermediate the elbow nor do Iclaim the disclosed means y the shaft, but what I do claim and desire tosecure by Letters Patent is,-

1. A cut-out valve comprising a pipe having an opening therein, a hollowopen-ended casing having an opening at one end within which is a valveseat through which the bore of said casing communicates with thebore ofsaid pipe, horizontally from the lower edges of vsaid casing, a flexibleplate of sheet metal having an opening therein the longitudinal edges ofwhich are flanged outwardlyv and laterallyand secured to the undersurface of said casingflanges, fitting said valve seat, actuating meansfor said valve mounted in the walls of the casing above the flanges ofboth casing and plate, and means for securing said plate to said pipe. ee v 2. A cut-out valve comprising al pipe having a longitudinallyelongated opening therein, an elbow having an lopening at one end withinwhich is a valve seat 'through which the bore ofsaid elbow communicateswith the bore of said pipe, flanges projecting outwardly and laterallyfrom the lower edges of said elbow, a flexible plate of sheet metalhaving an opening therein the longitudinal edges of which are flangedoutwardly and laterally, cured to the under surface of said elbowflanges, a valve having its rear Vend bent transversely .and pivotallymounted at the rear end of said valve seat, and means for securing saidplate to said pipe.
